TUB FOR WASHING MACHINES.

Application filed IanuaryM. 1324: Serial Noi seesaw.

The principal objects ofthe invention are to provide a tub which willeliminate splashing and the slopping of water about when wringing orremoving the clothes therefrom, and to devise a tub of sheet metalconstruction which will be easily kept clean, is of extremely lightweight and very strong and durable.

The principal features of the invention consist in forming a concaved ordished top to direct the wash water from splashing against the cover inthe washing operation and to lead the water into the tub when removingthe clothes or wringing, and further in flanging the edges of the endsinwardly in a curved flange and connecting same to the body in a doubleor look seam.

A still further feature consists in arranging an axial support in theform of dished discs secured to the radially ribbed ends and providedwith keystone shaped slots opening from the underside to receive taperedtrunnions.

In the drawings Figure 1 is a perspective view of'our improved tub.

Figure 2 is an enlarged side elevational and half vertical sectionalView.

Figure 3 is an enlarged end elevational and half vertical section.

Figure 4 is an enlarged perspective detail of one 01": the end supports.

The body 1 of the tub is substantially cylindrical having an opening 2in the top extending from end to end. Within the opening 2 is arranged atop sheet 3 which is secured to the body 1 with a double or look seam 4which gives great rigidity to the structure. The top is formed with acentral circular opening 5 into which a suitable cover is inserted.

The dished shape of the top drains any water falling on the top into thetub and thus prevents the slopping of wateroutside the tub when theclothes are being removed. A flange 6 is secured on the inner side ofthe top around the opening 5.

An opening 7 is formed in the bottom of the body 1 and extends from endto end and secured to the longitudinal edges of this opening by a lockseam 8 is a ridge piece 9 which isof an inverted V shape formed with arounded top 10 and filleted bottom portions 11 merging into the curve ofthe bottom of the body. The member 9 is drawn from sheet metal and theends 12 slope downwardlyand outwardly to: the line'oit the cylindriealbody and form a (3011+ tinuationof the end edges thereot.

f The ends 13' of the body 21l G"0fSl1bS1'Jtt11- tially circular formand are pressed with the rounded flanged edges 14 which are joined tothe end edges of the body and bottom ridge piece 9 in a lock seam 15. Bythus shaping the ends with therounded flanges the interior of the tub iscompleted without any sharp corners where dirt may lodge. Consequentlythe tub may be kept quite clean.

The ends 13 are strengthened by stamping therein a plurality of radialribs 16 which gdd stiliness and rigidity to the whole strucure.

Secured to the outer sides of the ends and centrally thereof are thedished discs 17 of heavy sheet metal. These discs are formed withflattened faces 18 and slots 19 are cut through the sloping portion andflattened ends opening from the bottom and having upwardly convergingside edges 20 forming keystone shaped slots.

Into the slots 19 are fitted cast metal blocks 21 of keystone shapehaving the converging sides 22 .shaped with a bevel thus forming adove-tail structure which when inserted into the slots 19 of the discs17 draws tightly into place, the inner faces of the blocks seatingagainst the ends 13 of the tub.

The blocks 21 are provided with gudgeon pins 23 which form the trunnionsupon which the tub is pivotally supported in suitable bearings. Thegudgeons are of course held in suitable hearings in a supporting frame,which is not shown and by reason of the taper structure of the blocksand the slots 19 of the end plates the tub may be easily removed and maybe as easily replaced and when in engagement the tub is very securelysupported.

In use the tub is oscillated by suitable means and the water and clothesare washed back and forth. The water washes up the rounded body 1 andstriking the inturned dished top 3 is directed downwardly and away fromthe cover and with the addition of the flange 6 the water is preventedfrom splashing out through the contact of the cover j oint, even thoughsaid joint may not be tight.

In the return swing of the tub the water and clothes strike the bridgepiece 9 and a rubbing and cleansing action occurs, the

water being forced through the fabrics. The rounded top of this bridgepiece with the filleted corners presents smooth rounded surfaces to theclothes in action so that they will not be torn or injured.

A tub constructed of sheet metal as'described is extremely light and istherefore operated with the minimum effort, the dishing and ribbing ofthe ends and the secur ing of the ends by double seams renders thestructure extremely rigid and strong and a very serviceable and alsogood appearing article is produced.

What We claim as Olll.ll1V811lliOl1 is 1. A tub for a washing machinehaving a rectangular opening in the top extending from end to end, a toppiece secured to the edges of said opening by a ribbed seam and havin acentral cover opening and being dishe inwardly to said cover opening, acover closing said opening and formed with a downwardly extending flangeadapted to engage the edge of said opening, and a support the tub andchannels formed in said tapered edges to receive the edge portion ofsaid tapered slots. to lock the tub against axial movement.
